These road signs are iconic. They’re noticeable but not distracting. They inform without imposing themselves. There’s something very soothing about them.

If you’ve ever taken the A10 motorway France between Bordeaux and Paris, it’s about a 500 km stretch that is fairly straight and, thus, a bit boring. But seeing these golden signs along the road was always a small event for me as a kid. They act as sporadic milestones: every time you see one, you know you’ve made progress and entered a new region.
